Some Amlogic boards store the Ethernet MAC address inside the eFuse. The Ethernet MAC address uses 6 bytes. The existing logic in meson_mx_efuse_read() would write beyond the end of the data buffer when trying to read data with a size that is not aligned to word_size (4 bytes on Meson8, Meson8b and Meson8m2). Calculate the remaining data to copy inside meson_mx_efuse_read() so reading 6 bytes doesn't write beyond the end of the data buffer.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
